Serial No. 422,331.

To all whom it may concern:

Be it known that I, GINO SOARAMUZZA, residing at Via Mazzini 2, Turin,Italy, have invented certain new and useful Im rovements in Fly-Wheels,of which the fol owing is a full, clear, and exact s ecification.

The present invention re ates to gas compressors with an hermeticallyclosed casing and the object of the invention is, first and foremost, torelieve the shaft of the weight of the flywheel in order, in this way,to avoid the possible oscillations and bending strains which arise fromthe flywheel itself.

At the same time the object of the invention is also to provide anarrangement which enables the outer bearing of the shaft to be omitted,for the purpose of considerably diminishing the size of the apparatus inthe direction of the length of the shaft, without thereby reducing thelength of the stufflng box which must allow the casing shaft to passthrough outward and must possess suflicient length to insure absolutetightness.

The realization of the object of the invention is attained by thefollowing construction:

A is the wall of the closed casing of the compressor, which carries theouter cylinder A of the stuffing box. This outer body is so turned andrepared that it can serve as the axle for the hub of the flywheel. Themasses of the rim and the hub are so arranged that a relief of theentire weight takes place onto the stufling box and through this ontothe casing itself. In order to transmit the move ment to the shaft, thehub is prolonged up to B B and provided with grooves C G into whichacross or star shaped piece of steel 1? is fitted. This piece is securedupon the shaft of the coin ressor by the aid of the wedges 1mm, an itsmovement in a transverse direction is prevented by a nut and lock nut,n, n. Rotary motion is therefore transmitted by the iece P continuouslyand without shocks an vibrations from the flywheel and belt pulley tothe shaft of the compressor.

To tighten up the stuffing box or to alter the interior of the stuflingbox the nut and lock nut "a, n, are slackened and the piece P can betaken out with great ease as stated above it is fitted with slightfriction onto the shaft and into the flywheel. As soon as the piece Phas been taken out, the cover of the stuffing box is accessiblestraightway and the piece S can be set in motion by means of a speciallyshaped key.

What I claim is:

1. A gas com ressor having a shaft passing therethroug and a stuflingbox surrounding the shaft, a fly wheel mounted on the stufling box, andmeans for connecting the fly wheel to the shaft.

2. A gas com ressor having a shaft passing therethroug and a stufflngbox surrounding the shaft, 2. fly wheel mounted to rotate on thestufiing box, and a coupling member for detachably connecting said shaftwith the fly wheel.

3. A gas compressor having a shaft passing therethrough and a couplingbox surrounding the shaft, said stufling box havin a packing chamber forthe shaft, a fly whee mounted on the stuffing box and a removablecoupling member connecting the shaft to the fly wheel so as to allowaccess to the packing chamber of the stufling box.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
